In the above video we set the residuals to be very small, at 1e-6. This effectively ensured that the calculation did not stop before before the 1500 iterations specified. A solution is deemed to have converged (and the calculation ends) when ALL residuals fall below the limit set. Although I forgot to input 1e-6 for k and omega, the outcome is the same because the x-velocity, y-velocity and z-velocity residuals had not reached 1e-6. |

For the first few hundred iterations you may see "reversed flow" being listed with each iteration. This will eventually disappear as the solution stabilizes and is nothing to be concerned over. This can easily be fixed in later iterations by moving the outlet further away from the wind turbine blade geometry. |
Solving may take a while depending on your computer and how it is set up, to give you an idea of the time it might take some run times are listed below.
